daylight cycle command

When entering the command /gamerule doDaylightCycle <false> then the aforementioned command but instead of <false> I used <true> to restore the default Day-Night cycle...

What I expected to happen was...:
The sky would continue to move as it normally should after entering the <true> version of the previously mentioned command.

What actually happened was...:
The Daylight cycle remained stuck in <false> mode.

Steps to Reproduce:
1. Enter command '/gamerule doDaylightCycle <false>' on any map.
2. Enter command '/gamerule doDaylightCycle <true>' on the same map and behold the second command has no effect on the sky/time.
